Alf/.l @il whoii'i. it may concern# itlknown that I, ISAAo ST. CLAIR GOLD- MAN, of Los Angelito, Los Angeles eounty, t -taililornizi, have invented certain new :nid

l'ollowino a si'ieeiliention.

y The object ol' my invention., toprovide :L lo'ek vhieh ea'nnot be successfully tempered with or pieked without breaking the leek.

A Yl'uither object is to provide et look of compact tively `small `Slot or opening;` for the insertion d ol' el keyend thus protecting;` the leek against the ineertion ol :in explosive or the entrance `oll dirtoir moisture. y l ,.lii'ilrthoiobject, is to provide :i leek espeillle` ol use `with it latch or holt end with right por lel't hond doors. l t `A,lui-ther object, is to `irovide :t leek using 2O on improved iorn'i ol' key mede ol compare.-

`:tively light sind thin meteriol, and to which the Vloree exerted in operating: the look, isopplied lengthwise on the key to move it edge- 'wise instead strain is usual in locks ol' this type.

`Uther ohieets oll the invention will eppem" l'rorn the following detailed deseriplion.

The invention consists generally in various eleonstruetions and eomhinilthms, .fill ne here- `inol'tor tlest-.l'ihed and particularly [minted l. l out in the elaims.

The plate 12 has e recess 1S in onoend and stops 19 on @eeh sido of said recess, Yl'ormed by turniiig,` up the end ofthe plate.

A series ol- Werde gli. gire pivoted .at one end in hearings 1 in the wellI oll the caminer end have opposite ends which are adopted lo enter the ieeess 1 S when the wards are moved into nlinement therewith. At other times, the Words are in the path ol' one 19, and positively prevent the retrfzetion ol' the plate 12 and' the Withdrawal ol' the holt. The Wards are normally held in the path ol the stop 1S) hy means of a series ol' springs 22 which are'iestened at one. end to the werds 80 and heer at their opposite ende on nA post 23. These springs :tre `all independent ol one :ne other, and each Werd is enrprthle ol movement independently olell the other werds. ',lhe werds lieve recesses 24 ih one edge whieh arel 85 held in eontnet with e.

D0 The,projeetioiis 'vitry in length hreordipgg to tho depth of the rer-,esses in the words, un( are. zularpted to enter the wards when the key is operated. .'lhe projections or points 1will .engage the werds with a, direet end pressure tud there will he no side twiht' or strain on them in the operation oll the key.' I am thusiihle to make thekey shank mui the `points ol' eolnpm'utively.light thin material :ind provide. a eorresi'iontliugly lim-row slot 100 in the lot-k easing to reeeive them..` This narrow slot Willumkeit preetieelly impossible to insert :L tool or any foreign substance into the lock, 'l`he key also` has: e her 25% adopted toslidoin rggiuidelll onA the key :md having' o beveled forward end ftlythnt is adapted to engage the Wall et one end ol' the key hole lSlot, and toreo the projeetions 37 'ons one oni adapted lo weer on smid lztleh und l the we rdel through the holes 27 into engagement with toosrllhtte them :ind :tdiost them ol the stops 75 adjust them inline to release the bolt.

in line with the recess inthe plate 12. The

bar 2S has a head 3] at one end lor convenience in forcing the ba r inwardly and pressing the key against the wards.

It will be noted, that the number of projections on the key must correspond to the number ol wards and that as each ward is independent ol' all. the others, it will be necessary to operate all ol them simultaneously to release the latch bolt. Any variation or inaccuracy therel'rn'e, in the length of the projections 27 resulting'in a vfailure to move a ward when the key is operated, will prevent the retraction ol' the bolt. rl`he wards must be exactly in line at the instant the bolt is thrown and it Awill be inpossible to insert a sullicient number ol' wires into the key hole opening to hold the several wards in their proper position and allow the bolt to be thrown. It will also be impossible to hold the wards in position to release the bolt without the use ol a perfectly formed key and as each ward is independent of all the others, it will not be possible to jar'or twist them to The wards are so situated that they toi-in a brace directly back ol' the latch bolt, and they also cover the holes communicating with the key slot, thus preventing anything like moisture or an explosive from entering the lock chamber. A post 32 having` a knob 33, is mounted in the casing and is provided with a wing 34 which when the post is revolved, is adapted to engage an inclined surface on the wards and 'force them away lroin the holes 27 and into alinement with the recess 18 in the end ol' the plate 12. As long as the wing 34 is 7n the position illustrated in Fig. I3, the wards will be locked open and the latch bolt be free to slide back and lorth. `ln Fig. (i, l have illustrated a series ol' removable points 2S to permit the combination ol' a high grade lock to be changed in case a key is lost or stolen. These points may bc removed l'rom the key and others ol' dillerent length substituted therefor. vl am thus able to change the combination ol' the lock and render the invent-ion applicable to high grade locks such as are user' on sales and vaults.

A lock for ordinary purposes can be Imade y with a single rigid bolt or with a `reversible latch as shown in the drawings. l have `illustrated the invention applied to a latch bolt, but it may bc used in connection with.

wards arranged therein, each'ward being holes corresponding in number to said wards and opposite the same respectively, a key having points adapted to enter said holes and engage said wards, means for forcing said key edgewise into engagement with said Wards and a latch bolt havin(T a recess to receive said wards, substantially as described.

4. A lock, comprising a casino', a bolt therefor, aseries of wards normally in the path of said bolt and preventing movement of the same, said wards having recesses in one edge and varying in depth, said casing having a slot to receive a key and a key having a series oi" points of' dill'erent lengthadapted to engage the edges of said wards in the recesses therein and means for movingl said key laterally to cause its edgeI to engage and act nate all of said wards simultaneously.

5. A lock having a key provided onv one edge with a series of points of varying length and a blade slidably mounted on the other edge of said key and-having a beveled outer end vthe engagement of said end with a iixed object causing the lateral movement of said key and endwise movement of the said points. i

4l. lhe combination, with a lock casing havingl a slot to receive a key and a wall provided with a series ol holes therein, of'a key composed ol comparatively thin material adapted to enter said slot and having a series ol' points formed on one edge, said points beingl adapted to enter the holes in said wall, a slide arricd by said keyand adapted to engage the wall ot said slot and force said points into said holes and a series of wards having their edges iii contact with said wall and normally concealing the holes therein.

7. A lock, comprising a casing having a .slot to receive a key and a wall provided i with a series of holes, o'l. wards having edges to contact with said wall and cover said holes, said wards being movable independently of 1 one another and spring devices lor holding' said rards in engagement 'with said wall.

S. A lock, comprising a casing, a sliding bolt therein, a series of wards movable independently ollv one another, a key having points to contact with said wards and means l'or moving said key laterally to actuate said wards.

.Y .l lock, having an opening to receive a key and a series oll holes in the wall inclosing said opening, a .series ol' wardsI movabh` indelll) penden tly of one another and yieldingly held against seid Wall, the edges of said wards closingr the holes in seid Wall, e `keg)T having e series of interchenweable points on one edge adapted to enter the holes in said well, and means for forcing seid points into seid holes and into engagement with seid werds.

10. `A lock, 'comprising e casing, e sliding holt therefor, e series of wards pivotelly erranged Within said easing and normally preventing movement of seid bolt, seid casing having au opening to receive e key, and. e Well with holes therein which are normali f closed hy said Wards, and e key having f means to enter said holes and ectuete seid Wards.

11. A leek having e sliding holt sind :L series of werds normally preventing movement of seid bolla, a key `fittinof seid lock and having points to Contact Wiih said wards respee tively and means for moving said key ina direction at right'angles substantially to its longitudinal exis, substantially as described.

12. A leek comprising e casing, :i bolt lherefor, e series of Wards, a Wall having holes therein `normally closed by said Wards, and a key having points adapted toinher the holes in seid Well und. zictuetessnd Wards.
